"It Depends" (as usual!)
If you have sufficient Arms (NOT GB!) then Image catalogs will be very
much faster plus you don't have to feed disks to the machine.
If you have few arms, physical media will win because the reading and
the writing is from/to the same overloaded arms.
So how many is "enough"? I generally say 8 Arms is good to go with
Image catalog. 4 arms is not enough. In between there it could go
either way.

Is there any big difference in installation time using catalogs 'vs'
physical media.
